Buick Excelle HRV timing tensioner abnormal sound solve

That's the position of the pump! If you don't find the location of the pump, it won't be useful to replace it with a new one! If you are repairing in an outside repair shop, it is no wonder that the car repair master does not understand!

The tensioner of the timing belt has a mark, the position of the pump is easy to shift slightly when the belt tensioner is replaced, the human eye can not see at all, the position of the pump has moved, the tensioner is naturally not tight enough, the mark of the tensioner is not good, there must be a sound, if you can't adjust the pump to the right position, you even if you change a hundred tensioners are useless! When we change the belt, we often have to adjust the pump, to have a special tool to adjust the best, generally this special tool only 4S shop, it is recommended that you go to the 4S shop, spend some man-hours to let the repairman get it for you!

Open the timing front cover to see if the tensioner pointer moves left and right when it starts, the movement is good, the tensioner is broken, if the tensioner is good, see if the belt is the same as the original belt, different belt changes, the idler belt is taken off and rotates left and right freely, the pump has no flower head, as far as I know, the general tensioner is imported, the movement inside is Japanese, and the shell is Australian.

The repair shop will only blindly replace the parts I tell you The new (domestic parts) is not necessarily good (the same batch of parts) Repair is not the same as repairing You buy the original original or buy the parts produced by the third-party manufacturer (Bosch company) The quality and specifications of the parts are the same as the original factory Do dynamic balancing The rotation plane is in the same horizontal plane.

Generally, the timing belt will be used for a long time, and the power of the car will disappear, accompanied by a strong abnormal sound, and there will be abnormal sound when starting again. service life; For example, timing belts will have different service cycles due to different materials and manufacturers, and they need to be replaced after a certain period of time. If the timing belt is faulty, there are generally signs:

Such as engine weakness, abnormal noise, can not start or start for a long time, etc. Therefore, the owner needs to consider this part when feeling the above phenomenon, of course, not only this, but also other parts. Due to friction with mechanical parts, dynamic heat, various vibrations or other components (such as transmission wheels), it will also reduce or weaken the service life of the belt, so after a certain period of time, refer to the manual standard, timely or advance inspection, maintenance, when found abnormal or belt cracking, lengthening, breakage, should be replaced in time.

In general, the standard of replacement is according to the requirements of the manual, and it is advisable to advance appropriately.

When it is installed, it does not have an arrow, and the arrow should be aimed at the tooth (that is, the lack on the tensioner) The general car is like this.

Precautions. The tensioning force of the tensioner should not be too small, too small will make the friction between the belt and the working wheel smaller, and eventually lead to belt slippage. Similarly, the tensioning force of the tensioner should not be too large, as excessive tensioning force will increase the load on the belt, resulting in damage to the belt and damage to the bearing of the working wheel.

The tensioner should generally be placed on the inside of the loose edge, so that the belt is only bent in one direction, and at the same time, it should be as close as possible to the large wheel, so as not to affect the wrapping angle of the small pulley too much. If the tensioner is placed on the outside of the loose edge, it should be as close to the small pulley as possible. The groove size of the tensioner pulley is the same as that of the pulley, and the diameter is smaller than that of the small pulley.

Adjust the angle of the pump, and the arrow on the tensioner is aligned with the notch.

Water pump, 100% good! I guess the people in the overhaul factory don't have that tool! By the way, are you sure you are right on the number of highways?

If that's right, the younger brother admires, the younger brother has repaired the Kaiyue not 1000 but also 800 never seen to run to more than 50W, that is, many more than 90% of the GL8 kilometers are also out of reach! If you're not far from us, I'll give you a kilometer to fix it for free!

Open the timing front cover to see if the tensioner pointer moves left and right when it starts, the movement is good, the tensioner is broken, if the tensioner is good, see if the belt is the same as the original belt, different belt changes, the idler belt is taken off and rotates left and right freely, the pump has no flower head, as far as I know, the general tensioner is imported, the movement inside is Japanese, and the shell is Australian.

That's how I've changed this car before. I couldn't change 5 tensioners in a row, and the sound was quiet after running for a while.

The first thing to say is that the tensioning wheels and adjusting wheels of Kaiyue cars are indeed very difficult and time-consuming. Secondly, this situation occurs in the car after it is good, which means that the maintenance master is not skilled at home and has not done a good job. Third, it is necessary to use original accessories.

If this is the case, you must restart it, otherwise the valve will be broken after a long time. It is recommended to find an experienced master who repairs Buick Kaiyue, and it may be able to solve the problem soon.

The repair shop will only blindly replace the parts I tell you that the new is not necessarily good (the same batch of accessories) repaired does not mean that it is repaired You buy the original original Dr. company.

The tensioner wheel is too tight, and the screws of the tensioner should be loosened after the timing belt is installed, otherwise it will buzz because the belt is too tight. You are a dangerous approach, in case the timing of the small shop is not on the belt is too loose to jump the teeth will top the valve, 4S shop to change the belt when the working hours cost 480, 50,000 kilometers to change once, buy a peace of mind.

If you want to change it in a regular 4S store, you may not be able to change the adjustment wheel, and it will cost more than 700 to change it in a regular 4S store.

I guess the timing isn't in tune, right? The quality of your accessories can also contribute to the sound.

Since it has been determined that it is a problem with the tensioner, let's change it, and at the same time, it is better to change the belt. Anyway, it is also a dismantling, and the belt is not much money (and the old belt has been pulled by the tensioner), if you do not change the tensioner, in case the bearing is stuck one day, the belt will definitely be finished.

Kaiyue's formal belt tensioner is composed of a bearing and a tensioner, there are 3 bolt fixing holes on the aluminum alloy bearing, which are fixed on the cylinder block with bolts, the structure of the tensioner is very peculiar, the bearing center of gravity adopts an asymmetrical design, that is, an eccentric bearing, when the belt is stressed, the amplitude of tensioning will make the eccentric tensioning of the tensioner work according to the force!

Assemble it the right way. Make sure the assembly is correct!

Hope it helps!
